It all depends on the length, and I can't find anywhere they publish the length of that bullet. Nosler is nice enough to put in their manuals that none of their .257 bullets will work in 1-14" twist Savage 99's, never seen another mfr do that.
If it measures over .95", it's probably not going to be great or maybe totally suck. Closer to .9" or less the better. A Partition with the lead tip cut off comes in at .915" and was shooting 3 shot groups of about 1.5" at 100yds. With the tip on the bullet was measuring 1.04" and was shooting 5" to 8" groups at 100yds.
